BACKGROUND: Endomyocardial biopsy (EMB) has been defined as the gold standard method for surveillance of rejection after heart transplantation, and it has also been used in the diagnosis of myocarditis and the unknown causes of cardiomyopathies. The procedure, however, is not free from complications. Access through the jugular vein or the femoral vein is the standard approach. In this study, we performed biopsies by using a long, curved sheath and evaluated the rate of complications with this technique...

Viral infections of the heart cause serious clinical problems, either as infectious myocarditis, which usually is a consequence of acute infection or as idiopathic dilated cardiomyopathy, resulting rather from a chronic infection. This minireview presents an up-to-date view on pathomechanisms of viral infection of the heart tissues, the role of immune system in controlling infectious process at its various stages and current possibilities of recognizing viral infection of the heart with use of both cardiological and virological methods...

Acute myocarditis may lead to left ventricular dysfunction and subsequent need for cardiac transplantation. We describe a 15-month-old child who presented with right heart failure of unclear cause. Echocardiography showed normal left ventricular function; however, right ventricular function was markedly reduced. The patient required extracorporeal membrane oxygenation followed by placement of a right-sided Berlin EXCOR ventricular assist device. There was little recovery, and the child underwent cardiac transplantation...

BACKGROUND: Coxsackieviruses are members of a group of viruses called the enteroviruses, which may cause respiratory and gastrointestinal symptoms, erythema, meningoencephalitis, myocarditis, pericarditis, and myositis. Unilateral acute idiopathic maculopathy caused by coxsackievirus A16 has been associated with hand, foot, and mouth disease, but only a few reports describe retinitis associated with coxsackievirus serotype B3 or B4. We report a case of bilateral multifocal obstructive retinal vasculitis that developed after coxsackievirus A4 infection...

People in southern Taiwan experienced two major dengue outbreaks in 2014 and 2015. The mortality and clinical features were very different between these 2 years. Dengue virus serotype 1 (DENV-1) caused epidemic outbreak in 2014 and DENV-2 was predominant in 2015. The characteristics of dengue hemorrhagic fever (DHF) cases in the 2 years was analyzed. We conducted a retrospective chart review to analyze the clinical and laboratory features of 206 adult patients with DHF in southern Taiwan in 2014 and 2015. The mortality rate of DHF cases in 2015 was higher than that of cases in 2014 (38...

We present a case of a 21-year-old man presenting with sharp left-sided chest pain. A CT pulmonary angiogram was negative, ECG was unremarkable and a mild troponin rise was observed. Myocarditis was suspected as the most likely diagnosis, particularly in view of the patient's previous diagnosis of myocarditis 3 years prior. A cardiac MRI was indicative of an acute mid-anterior myocardial infarction (MI) and an old inferior MI with an associated aneurysm. A subsequent angiogram revealed a subtotal occlusion in the second diagonal artery, likely precipitated by homozygous factor V Leiden...

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease characterized by microvascular abnormalities, inflammation and fibrosis. We hypothesized that myocarditis may be diagnosed in asymptomatic SSc, undergoing routine cardio-vascular magnetic resonance (CMR) for fibrosis assessment, using the Lake Louise criteria: T2 ratio, early (EGE) and late gadolinium enhanced (LGE) images. METHODS: Eighty-two asymptomatic SSc, diagnosed according to American College of Rheumatology criteria, aged 43 ± 5 yrs...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is carried to human hosts by infected ticks. There are nearly 30,000 cases of Lyme disease reported to the CDC each year, with 3-4% of those cases reporting Lyme carditis. The most common manifestation of Lyme carditis is partial heart block following bacterial-induced inflammation of the conducting nodes. Here we report a 45-year-old gentleman that presented to the hospital with intense nonradiating chest pressure and tightness. Lab studies were remarkable for elevated troponins...

In the recently an increase morbidity inflammatory bowel disease, including ulcerative colitis was observed. The use of purine analogs and their metabolites are associated with a higher incidence of infections in this group of patients. Listeriosis is an infectious disease caused by a relatively anaerobic gram-positive bacteria - Listeria monocytogenes. Common symptoms include fever, nausea, vomiting and diarrhea, but these pathogens can also cause myocarditis, central nervous system infections, including brain abscesses and sepsis...

Objective To analyze the migration and expression of CD34(+)VLA-4(+) cells under the induction of vascular cell adhesion molecule-1 (VCAM-1) in a murine model of acute viral myocarditis (VMC). Methods Frequency of CD34(+)VLA-4(+) cells in the myocardial tissues and peripheral blood were examined by flow cytometry. The mRNA and protein of VCAM-1 in the myocardial tissues were analyzed by real-time quantitative PCR and Western blotting. Results In the acute VMC mice, CD34(+)VLA-4(+) cell population in the myocardial tissues significantly increased at day 3, peaked at day 7, and then decreased, but it was still higher than that in the control group at day 14 and 28...

BACKGROUND: The clinical autopsy is the ultimate medical service for a patient and plays a crucial role in the education of physicians and other medical personnel, as well as in the context of quality control. Nevertheless, the number of autopsies is constantly decreasing. Numerous factors, such as the personal attitude of relatives and also clarification of relatives, as well as the increasing application of imaging methods while the patient is still alive, play a central role in this decline...

Treatment options for metastatic melanoma have changed substantially in recent years. Targeting immune checkpoints has improved prognosis of melanoma patients. For melanomas harboring BRAF mutations, inhibition of the mitogen-activated protein kinase pathway is a promising therapeutic option. Combined BRAF and MEK inhibition improves progression-free and overall survival. This article is protected by copyright. All rights reserved.

PURPOSE: Chronic diabetes is associated with cardiovascular dysfunctions. Diabetic cardiomyopathy (DCM) is one of the serious cardiovascular complications associated with diabetes. Despite significant efforts in understanding the pathophysiology of DCM, management of DCM is not adequate due to its complex pathophysiology. Recently, involvement of protease-activated receptors (PARs) has been postulated in cardiovascular diseases. These receptors are activated by thrombin, trypsin, or other serine proteases...

BACKGROUND: Although rare, cardiac sarcoidosis (CS) is potentially fatal. Early diagnosis and intervention are essential, but histopathologic diagnosis is limited. We aimed to detect Propionibacterium acnes, a commonly implicated etiologic agent of sarcoidosis, in myocardial tissues obtained from CS patients. METHODS AND RESULTS: We examined formalin-fixed paraffin-embedded myocardial tissues obtained by surgery or autopsy and endomyocardial biopsy from patients with CS (n = 26; CS-group), myocarditis (n = 15; M-group), or other cardiomyopathies (n = 39; CM-group) using immunohistochemistry (IHC) with a P...
